Stress-free navigation covers the basic introductory elements clearly and simply for novices, and progresses through more advanced techniques for experienced navigators, so that there is something for everyone, whatever your skill level. And most importantly, Stress-Free Navigation is tailored to modern methods, using GPS, electronic chart plotters, apps and integrated weather and tide programs. Each chapter starts with the electronic and moves to the ‘traditional’ to explain what the clever-looking stuff is telling us.
